BURNER.

Specication of Letters Patent.

Application led June 11, 1917. Serial No. 174,158.

To all whom it may concern.'

Be it known that I, WILLIAM S. Davis, a citizen of the United States,residing at Sacramento, in the county4 of Sacramento and State ofCalifornia, have invented certain new and useful Imprpvements inBurners, of which the following is a specification, reference being hadto the accompanying drawings.

This invention relates to certain improvements in liquid fuel burnersand it' is an object of the invention to provide a device of thisgeneral character having novel and improved means whereby an intenseheat may e generated and wherein the creation of odor issubstantiallyentirel eliminated It is also an objectof the inventiontofprovide a burner of this general character having novel andimproved-means whereby the requisite mixture of air is assured forsupporting combustion and creating suiiicient draft to form a flame ofmaterial length.

The invention consists in the details -of construction and in thecombination and arrangement of the several parts ofmy vimproved burnerwhereby certain important advantages are attained and the device isrendered simpler, less expensive and otherwise more vconvenient andadvantageous for lflsall as will be hereinafter more fully set The novelfeatures of the invention will hereinafter be deinitely claimed.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wlherein-Y l l Figure 1 is a diagrammatic view partly inelevation and partly in section illustrating a burner constructed iniaccordance with an embodiment of my' invention; l

Fig. 2 is a sectional Flg. Sis a fragmentary elevational view with partsomitted illustrating a slightly modified form of my improved burner.

As disclosed in the accompanying drawings, 1 denotes a supporting baskethaving its upper end opened and provided adjacent its upper end with anannular series of materially large openin 2. As disclosed in Fig. l, thebasket 1 1s tapered toward the bottom and isseated within a suitableopening in a support S, said support being preferably the lower end of aheating device as v1ew taken substan- "tially on the line 2-2 of Fig. 1;and

M which comprises a hollow body providedat its margin with an annularseries of restricted openings 4. The center of the burner M is providedtherethrough with a threaded opening 5 and in which is engaged thedepending boss 6 arranged' at the axial center of the supplementalburner B lpositioned above the main burner M and in predetermined spacedrelation thereto. The supplemental urner B is-falso of a predetermineddiameter less than the diameter of the main burner M. The supplementalburner' B is also hollow and provided at its marginal portion with anannular series -of restricted'- openings 7. A In communication with thechamber of each of the burners M and B is a supply-pipe 8 and 8',respectively, leading from a common source of fuel supply as indicatedby the pipe 9.'- Interposed in the pipe 8 coacting with the supplemental`burner S is a needle valve 10 adapted to be automatically operatedthrough the medium of a thermostat T whereby the operation of the burnerB may be regulated in accordance with the requirements of practice. Thesecond pipe 8 has interposed therein the manually operated needle valve11 for controlling the flow of fuel through said second pipe 8. Each ofthe pipes 8 has also interposed therein the access within the plpe 8 inorder to observe the llow of the fuel therethrough.

Surrounding the burner M is a sleeve 14 of a lenv h to terminate abovethe openings 2 herein efore referred to but below the top or o en end ofthe basket 1. Positioned within the sleeve 14 and concentric thereto isa second sleeve 15 which surrounds the glass l2 to afford visual topermit the air entering through the openings 2 in the basket 1 tolproperly support combustion while the sleeves 14, 15 and 16 coact toafford flues to result in sufli'cient draft being created as to causethe flames of the burners M and B to be of material length. It has beenfully demonstrated in practice that the openings 2, which are materiallyin excess of the areas of the restricted openings 17 coact with therestricted openings 17 in creating a flame free from smoke and which canbe maintained'at a comparatively small cost. In practice it has beenfou'nd that theltlames of the burners M and B can be maintained on apint of fuel per hour. v

The upper face of the burner B at its axial center is provided with theupstanding lug 1.8 to afford means whereby a wrench or other implementmay be engaged with said burner B when it is desired to apply or removethe same.

The form of my invention as illustrated in Figs. 1 and 2 is particularlyadapted for use in connection with a water heater as embodied in mycopendin application executed on even date herewit I have found,however, in practice that my improved burner may be employed withconvenience and facility in connection with the creation of dry heat. Inthis latter luse the burner is adapted to be connected directly with thelower end portion of a flue F as particularly illustrated in Fig. 3. Inso using the upper portion of the basket la at each side thereof 1sprovided with an outstanding pin 19 with which is adapted to coact asubstantially L shaped lug 20 depending from the flue F.

From the foregoing description, it is thought to be obvious that aburner constructed in accordance with my invention is of an extremelysimple and comparatively inexpensive nature and is particularly Welladapted for use by reason of the convenience and facility with which itmay be assembled, and it will also be obvious that my invention issusceptible of some change and modification without material departurefrom the principles and spirit thereof and for this reason I donot wishto be understood as limiting myself to the precise arrangement andformation of the several parts herein shown in carrying out my inventionin practice, except as hereinafter claimed.

I claim:
